(b) Feeding
1 When hopping is completed, the registration motor turning in direction "b" (counter-clockwise direction) drives the
registration roller to advance the paper (in this case, the hopping gear also turns, but the hopping roller is prevented
from turning by the one-way bearing).
2 The paper is further advanced in synchronization with the print data.
(2) Charging
Charging is actuated by the application of the DC voltage to the charge roller that is in contact with the image drum
surface.
